My ex boyfriend cheated on me and then I took some time and I eventually forgive him because I don't hold grudges over situations I cannot change but I expressed that we shouldn't be together. Then a few months later down the line we decided to get back together and I discovered that he was messaging other females and flirting and I said that was enough. I did however during the first break up visited one of his male friends however him and I did not have any type of sexual contact or anything of that nature because I respect myself more than the dilemma to not have did anything with him. His male friend told him I came to see him then lied to him and told him we had sex then clears it up and say we didn't but he could have if he wanted to although that was a lie and he acts as if he is angry about the situation and continues to mention it. Must I mention that this was after he cheated on me I just wanted him to feel how I felt after being cheated on and being faithful although he's not seeing it from my perspective. I'm not saying what I did was right or anything or needing any justification. His mother really wants me to be pregnant with her grandchild however him and I do not see eye-to-eye all the time but when we're good we're great but then it's the cheating and abuse part plus lies that I cannot deal with. What should I do?
